If you see “Do not enter” or “Wrong way” signs, or if you see red bumps on the road, then you are entering the road in the wrong direction. K-turn and return where you came from.
Be wary of curves in the road that you will have to maneuver around. If a vehicle is at the base of a hill, it should give way to traffic coming towards them. If you see a car backing up on a narrow road, you will probably need to back up as well to a place where you can allow for oncoming traffic to pass you safely.
In most of North America and Europe, allow traffic to pass you on the left side of the road. In most of Australia, Japan, India, Pakistan, and the UK, allow traffic to pass you on your right.
